CD4511 7-Segment Driver IC

CD4511 7-Segment Driver IC

CD4511 7-Segment Driver IC combines the low quiescent power dissipation and high noise immunity feature of CMOS with NPN bipolar transistor, which is capable of giving output current of 25mA. Mainly this IC is used for lighting up or driving various types of display like 7-segment, low voltage fluorescent display and incandescent display. But this IC is mainly used for driving the 7-segment display
